I traveled through hundreds of worlds at once

"That's it!" Inuyasha and Ihui, who left the demon-killing village, spent nearly a day climbing over one mountain valley after another, crossing a distance of hundreds of miles, and came to an active volcano with flowing magma.

"This place is really remote. If it weren't for Inuyasha leading the way, I really didn't know there was such a place near Musashi Province." Ihui followed Inuyasha and carefully jumped over the hot magma, and lightly came to the halfway point of the active volcano, in front of a huge fishbone cave.

Outside the cave, a three-eyed black cow was lying on the hot ground and sleeping soundly. Inuyasha saw the three-eyed cow here.
